Like going from PSU to Lt Col. At the most important units, they always have a handpicked loyalist in charge if possible and several eyes and ears working in a unit. They were on "the team" the whole time. Command can't play favorites as easily if someone rats on you. Egotists have a deep psychological need for brown nosing loyalists who are usually not that bright or ethical and need to be rescued like Betts was from jail, at least for a while.
